62 TBird Master Cylinder

[biggieou]

Swapping to disc brakes on the bird. Having issues with the MC that came in the kit - way too big. Was curious what other options there are out there for MCs that would work? Doesn’t need to me stock looking.

[KULTULZ]

What kit did you buy and what exactly is wrong?

[biggieou]

Don’t know the kit, adapter and hardware worked for the calipers, rotors were wrong, bearings were wrong.

As Kultulz asked, we need more details - where'd you get it from, any info like did they have a part number or description of the kit, are you using the original Midland-Ross brake booster or something else, etc.? Pictures would be MOST helpful. Inquiring minds want to know...

[dmsfrr]

If it's that wrong, doesn't fit and has no useful information about it...
maybe you should return it for a refund, or just cancel payment.

Maybe it has one of those scrubby CORVETTE ugly MC's and you want it to look FORD OEM?

You have to be careful on some of these kit sellers as they have no clue. Throw GM parts in a box and ship it.

I’m thinking this was the case.

What modern style MCs will work with the original booster?

Well, that's the problem. What booster style did they include with the kit? A FORD MC might not mount to it. If you choose a FORD MC, you may have to use a different booster.

Can you show photos?

Yeah I’ll grab some pics later today. Looks like a GM MC to me.

My booster is good. Was curious if a Mustang, LTD MC would bolt to the stock booster.

Yeah I’m trying to find a shorter booster

The booster you are showing is a 1968 MUST? How deep was the booster that came on the car?

[biggieou]

No that’s the factory tbird booster

[flatrod]

What's wrong with the original booster? Are you adding rear disc brakes? Kultulz is right the kit master cyl is GM usually for 4 wheel disc brakes. The Mustang master cyl you show is for drums (rear) disc on the front. The larger rear section on the Mustang unit is for the front brakes, smaller is for the rear drums. What's wrong with using the original booster and the Mustang MC you have?

[biggieou]

Ok so I think there’s some confusion going on here, most likely due to my description of the issue. We were just fitting up that MC from the Mustang to see if it would work. It wasn’t already mounted on the car. Original booster works fine.

[KULTULZ]

Can you give me the depth of the original booster?

[biggieou]

Thanks everyone. Sorry, wasn’t able to get out and measure it yesterday. I’m thinking the bracket at the back is what is killing me for space. Need to research these links. You all are the best. More to come!

I started researching this swap for someone with a '62 Bird and may wind up with the car myself. Those crappy Corvette masters, I would not use one. I liked that Ford dual master that was early in the thread. All better if you can match up the back of it with the OG one.


The car I'm interested in has drum brakes, new master and booster. I would leave it as is and make sure everything in the drums was ok. I saw something on the brace replacement, someone used one from a '64-'66 Bird or maybe modified it as well. The brace is pretty essential to the structure of the car.


If I can find a good link, I'll post it.

[biggieou]

Still working on this. Been pretty frustrating. Followed one of the links supplied and set up the new booster with the old mount and the darn from brake line port is just slightly too close to the shock tower. Going to try a 68 Mustang MC with the booster and see if that fits. Might have to put a remote fill cap on to get rid of the tall lid and bail.

Question I have is, the booster is set up for a shallow MC, the Mustang MC is deep bore. How can I convert the booster to have a longer rod?

Don't know about your case, but in the past I've had masters that came with a "plug" you put in the bore. Used only with the power booster. Was machined to accept the short rod and the bore.

This is likely the answer. Even a piece of steel the right diameter would work. It does help to have friends that work in machine shops. Just measure up the differences to come up with the plug length.


There is another Ford master that puts the lines on the inside. Look up Dorman M97934, but it may have a 7/16-20 port on it, you'll need that fitting. Not a big deal since you'll have to fab a line at some point.
